Oh, I missed this information. So this means that, after having run once the balancer in compat mode, if you add new OSDs you MUST manually defined the weight-set for these newly added OSDs if you want to use the balancer, right ?
This is an important piece of information that IMHO should be in the ceph documentation when the balancer is discussed Thanks again for your help !
